How to Make Snuggly Slippers from Old Sweaterscomments (19) February 22nd, 2013
Clean up the shape around your toes so it's more of a smooth curve.
Draw the shape of the opening where your foot will go in. It should begin about 3-1/2 inches from the toe end and follow the shape of the sides and heel about 1 inch in from the outer edge. The sides and heel should be a consistent width. Don't worry if the opening seems small; it will stretch.
Finally, I added a 1/4-inch seam allowance around the outer edge of the foot shape, but next time I'll probably skip this step because my slippers came out a bit bigger than I'd like. Sweaters are stretchy, so it's better to make the pattern small so that it hugs the foot.
